Tom, there are alot of boats for sale you can still buy a twin, triple or four screw boat.

Bob, I wonder if the engines have ever been worked on or changed, I am working with a guy up in the oakland bay area that has a boat his grand father bought before ww II that has a single gray marine 6-71 with over 53,000 hrs on it and the records dont show that the head has ever been off of the engine. It takes a little either to start it but it runs clean and even on all 6.
